Handle new windows and tabs

A link with target="_blank" opens a new tab, and every later driver call still targets the old one until you switch. BasePage's withNewWindow(opener, body) does the handle bookkeeping: it runs opener (the click), switches to the window that opened, runs body there, closes it, and switches back to the original window — even if body throws.

FooterPage.java

public void verifyTermsOpensInNewTab() {
    withNewWindow(
        () -> click(By.linkText("Terms")),
        () -> assertEquals(driver.getTitle(), "Terms of Service"));
    // back on the original window here
}

withNewTab(opener, body) is an alias — browsers open both the same way.

If no new window appears within timeouts.explicit, a TimeoutException is thrown and body does not run, so a link that silently fails to open fails the test rather than passing it.
